"Swap with clipboard" command does not work and breaks range selection

Bug description

The swap with clipboard command has broken badly between 4.0.1 and 4.0.2. It correctly pastes the current clipboard contents, but rather than load the clipboard with the contents fo the destination, it appear to corrupt the clipboard in a strange way, where after attempting to paste it, nothing appears to happen, but you then become unable to make range selections until you save/reload.

Steps to reproduce

1. new score, Treble Clef template, 4/4
2. enter quarter notes C C C C | D D D D into the first two measures
3. Select the first measure
4. Ctrl+C to copy
5. Select the second measure
6. Ctrl+Shift+X to swap with clipboard
7. Select the third (empty) measure
8. Ctrl+V to paste

Result: nothing is pasted, which is bad enough, but worse, you are now completely unable to make a range selection of any kind. Clicking a measure, Click/Shift+click, Shift+Right, Shift+drag, etc - range selections just cannot be made anymore. Save/reload fixes the inability to select, but the swap operation itself will still have failed.
